Add range-loop based iterators

[sticilface]

Any chance of adding compatibility for c++11 range loops?

Id like to be able to iterate over the data using

for (auto & item : cirBuffer ) 
{
...
}

thanks

You can submit a pull request containing the necessary changes, but as this library is intended for limited memory devices, watch out for any increment on program space or memory use: we strive for efficiency, not all around ease of use.
